QSslCertificate Class Reference

Member Function Documentation

QSslCertificate::QSslCertificate ( QIODevice * device, QSsl::EncodingFormat format = QSsl::Pem )

Constructs a QSslCertificate by reading format encoded data from device and using the first certificate found. You can later call isNull() to see if device contained a certificate, and if this certificate was loaded successfully.

QSslCertificate::QSslCertificate ( const QByteArray & data = QByteArray(), QSsl::EncodingFormat format = QSsl::Pem )

Constructs a QSslCertificate by parsing the format encoded data and using the first available certificate found. You can later call isNull() to see if data contained a certificate, and if this certificate was loaded successfully.

QSslCertificate::QSslCertificate ( const QSslCertificate & other )

Constructs an identical copy of other.

QSslCertificate::~QSslCertificate ()

Destroys the QSslCertificate.

QMultiMap<QSsl::AlternateNameEntryType, QString> QSslCertificate::alternateSubjectNames () const

Returns the list of alternative subject names for this certificate. The alternate subject names typically contain host names, optionally with wildcards, that are valid for this certificate.

These names are tested against the connected peer's host name, if either the subject information for CommonName doesn't define a valid host name, or the subject info name doesn't match the peer's host name.

See also subjectInfo().

void QSslCertificate::clear ()

Clears the contents of this certificate, making it a null certificate.

See also isNull().

QByteArray QSslCertificate::digest ( QCryptographicHash::Algorithm algorithm = QCryptographicHash::Md5 ) const

Returns a cryptographic digest of this certificate. By default, an MD5 digest will be generated, but you can also specify a custom algorithm.

QDateTime QSslCertificate::effectiveDate () const

Returns the date-time that the certificate becomes valid, or an empty QDateTime if this is a null certificate.

See also expiryDate().

QDateTime QSslCertificate::expiryDate () const

Returns the date-time that the certificate expires, or an empty QDateTime if this is a null certificate.

See also effectiveDate().

QList<QSslCertificate> QSslCertificate::fromData ( const QByteArray & data, QSsl::EncodingFormat format = QSsl::Pem ) [static]

Searches for and parses all certificates in data that are encoded in the specified format and returns them in a list of certificates.

See also fromDevice().

QList<QSslCertificate> QSslCertificate::fromDevice ( QIODevice * device, QSsl::EncodingFormat format = QSsl::Pem ) [static]

Searches for and parses all certificates in device that are encoded in the specified format and returns them in a list of certificates.

See also fromData().

QList<QSslCertificate> QSslCertificate::fromPath ( const QString & path, QSsl::EncodingFormat format = QSsl::Pem, QRegExp::PatternSyntax syntax = QRegExp::FixedString ) [static]

Searches all files in the path for certificates encoded in the specified format and returns them in a list. must be a file or a pattern matching one or more files, as specified by syntax.

Example:

 foreach (const QSslCertificate &cert, QSslCertificate::fromPath("C:/ssl/certificate.*.pem", QSsl::Pem,
                                                          QRegExp::Wildcard)) {
     qDebug() << cert.issuerInfo(QSslCertificate::Organization);
 }

See also fromData().

Qt::HANDLE QSslCertificate::handle () const

Returns a pointer to the native certificate handle, if there is one, or a null pointer otherwise.

You can use this handle, together with the native API, to access extended information about the certificate.

Warning: Use of this function has a high probability of being non-portable, and its return value may vary from platform to platform or change from minor release to minor release.

bool QSslCertificate::isNull () const

Returns true if this is a null certificate (i.e., a certificate with no contents); otherwise returns false.

By default, QSslCertificate constructs a null certificate.

See also isValid() and clear().

bool QSslCertificate::isValid () const

Returns true if this certificate is valid; otherwise returns false.

Note: Currently, this function checks that the current data-time is within the date-time range during which the certificate is considered valid, and checks that the certificate is not in a blacklist of fraudulent certificates.

See also isNull().

QString QSslCertificate::issuerInfo ( SubjectInfo subject ) const

Returns the issuer information for the subject from the certificate, or an empty string if there is no information for subject in the certificate.

See also subjectInfo().

QString QSslCertificate::issuerInfo ( const QByteArray & tag ) const

Returns the issuer information for tag from the certificate, or an empty string if there is no information for tag in the certificate.

See also subjectInfo().

QSslKey QSslCertificate::publicKey () const

Returns the certificate subject's public key.

QByteArray QSslCertificate::serialNumber () const

Returns the certificate's serial number string in decimal format. In case the serial number cannot be converted to decimal format (i.e. if it is bigger than 4294967295, which means it does not fit into 4 bytes), its hexadecimal version is returned.

QString QSslCertificate::subjectInfo ( SubjectInfo subject ) const

Returns the information for the subject, or an empty string if there is no information for subject in the certificate.

See also issuerInfo().

QString QSslCertificate::subjectInfo ( const QByteArray & tag ) const

Returns the subject information for tag, or an empty string if there is no information for tag in the certificate.

See also issuerInfo().

QByteArray QSslCertificate::toDer () const

Returns this certificate converted to a DER (binary) encoded representation.

QByteArray QSslCertificate::toPem () const

Returns this certificate converted to a PEM (Base64) encoded representation.

QByteArray QSslCertificate::version () const

Returns the certificate's version string.

bool QSslCertificate::operator!= ( const QSslCertificate & other ) const

Returns true if this certificate is not the same as other; otherwise returns false.

QSslCertificate & QSslCertificate::operator= ( const QSslCertificate & other )

Copies the contents of other into this certificate, making the two certificates identical.

bool QSslCertificate::operator== ( const QSslCertificate & other ) const

Returns true if this certificate is the same as other; otherwise returns false.
